On May 4, 1968, Dancer's Image crossed the finish line at Churchill Downs to win the 94th Kentucky Derby. Yet the jubilation ended three days later for the owner, the jockey and the trainers who propelled the celebrated thoroughbred to victory. Amid a firestorm of controversy, Dancer's Image was disqualified after blood tests revealed the presence of a widely used anti-inflammatory drug with a dubious legal status. Over forty years later, questions still linger over the origins of the substance and the turmoil it created. Veteran turfwriter and noted equine law expert Milt Toby gives the first in-depth look at the only disqualification in Derby history and how the Run for the Roses was changed forever.

In 2021, horse racing's most recognizable face - Hall of Fame trainer Bob Baffert - had five horses that failed postrace drug tests, including that year's Kentucky Derby winner, Medina Spirit. While the incident was a major scandal in the Thoroughbred racing world, it was only the latest in a long string of drug-related infractions among high-caliber athletes. Stories about systemic rule-breaking and "doping culture" - both human and equine -have put world-class athletes and their trainers under intense scrutiny. Each newly discovered instance of abuse forces fans to question the participants' integrity, and in the case of horse racing, their humanity. In Unnatural Ability: The History of Performance-Enhancing Drugs in Thoroughbred Racing, Milton C. Toby addresses the historical and contemporary context of the Thoroughbred industry's most pressing issue. While early attempts at boosting racehorses' performance were admittedly crude, widespread legal access to narcotics and stimulants has changed the landscape of horse racing, along with athletic governing bodies' ability to regulate it. With the sport at a critical turning point in terms of doping restrictions and sports betting, Toby delivers a comprehensive account of the practice of using performance-enhancing drugs to influence the outcome of Thoroughbred races since the late nineteenth century. Paying special attention to Thoroughbred racing's purse structure and its reliance on wagering to supplement a horse's winnings, Toby discusses how horse doping poses a unique challenge for gambling sports and what the industry and its players must do to survive the pressure to get ahead.

It was a cold and foggy February night in 1983 when a group of armed thieves crept onto Ballymany Stud, near The Curragh in County Kildare, Ireland, to steal Shergar, one of the Thoroughbred industry's most renowned stallions. Bred and raced by the Aga Khan IV and trained in England by Sir Michael Stoute, Shergar achieved international prominence in 1981 when he won the 202nd Epsom Derby by ten lengths -- the longest winning margin in the race's history. The thieves demanded a hefty ransom for the safe return of one of the most valuable Thoroughbreds in the world, but the ransom was never paid and Shergar's remains have never been found. In Taking Shergar: Thoroughbred Racing's Most Famous Cold Case, Milton C. Toby presents an engaging narrative that is as thrilling as any mystery novel. The book provides new analysis of the body of evidence related to the stallion's disappearance, delves into the conspiracy theories that surround the inconclusive investigation, and presents a profile of the man who might be the last person able to help solve part of the mystery. Toby examines the extensive cast of suspects and their alleged motives, including the Irish Republican Army and their need for new weapons, a French bloodstock agent who died in Central Kentucky, and even the Libyan dictator, Muammar al-Qadhafi. This riveting account of the most notorious unsolved crime in the history of horse racing will captivate serious racing fans and aficionados as well as entertain a new generation of horse racing enthusiasts.
